What would cause my barely used green bearing to do this?

7-1/4, 9-1/4, Ford 9in, GM 12 bolt, every FWD car ever made. All use ball or straight roller bearings, no taper bearings to be found.

There's no downside to running green bearings, there are millions upon millions more cars out there running "green" type bearings vs a tapered bearing. Plenty of them high powered.
Yeah, with different axle designs.....

Goddamn it....sucked in again...
